IMPROVEMENT IN CULTIVATORS.

To all whom it may concern f Be it known that we, WILLLAM F. COULTER, G. F. TRABUE, and W. A. LowREY, all of Hardinsburg, in the county of Washington, and State of Indiana, have invented certain Improvements in Gultivators; and We do hereby declare that the following is a full, clear, and exaet description thereof', reference being had to the accompanying drawings, making a part oi' this specilication, in which- Figure 1 is an elevation of one side of the improved cnltivator.

Figure 2 is a top view of the cultvatgr.

Figure 3 is an elevation on therear end ofthe machine.-

Figure 4 is a longitudinal section, taken in a vertical plane, through the centre of the improved machine.

Similar letters of reference indicate corresponding v parts inthe several gures.

This invention relates to certain novel improvements on that class of cultivators having the shovels arranged beneath, and carried by means of a ame which is mounted upon two t1ansportingwheels.

The nature of our invention consists in arranging beams, which carry cultivator-shovels, beneath the frame of a hed-wheel carriage, so that the beams and shovels are free to vibrate in vertical planes, and thus conformto the undulations of the ground passed over, said beams being pivoted to laterallyebraced pendants at their front ends, so that these ends can b'e adjusted vertically, for regulating the pitch ofthe shovels and the depth they should run in the ground, and said beamsbeing connected, by means of staples near their rear ends, to laterally-ad] ustable pendent braces, which will allow free vertical movements of the rear ends of the beams, but eiectually prevent them from being thrust laterally out of place, as will be hereinafterexplained.

Our invention also consists in providing each shovelcarrying beam with a bail or staple, n ear its rear end, and in having laterally-springing suspension-hooks applied to the `axle of the transporting-wheels, which hooks are adapted forreceiving the said staples, and serving as supports for the-rear ends of the shovelcarrying beams, when it is desired to hold the shovels up' free from the ground, out' of operation, as will be hereinafter explained.

To enable others skilled in the art to understand our invention, we will describe its construction and operation.

. In the accompanying drawings, A A represent two transportingfwheels, which are applied on the ends of an axle-tree, B, the central portion of which may be bent, so as to elevate it above a plane coinciding with tthe'axes of the wheels A, as shown in gs. 3 and 4.

' Upon this axle rest and are iirmly secured the hounds C C, which extend back in rear of the axle, and serve -as supports for a seat. and brace-board, D, and which converge toward their front ends, and receive between them the rear end of draught-poleE, asshownin g. 2. These hounds C Gare thus adapted to serve as the draught-frame of the machine,and, in consequence of their shape and connections, they abrd a very ,light butsubstautial frame.

Beneath the axle and hounds are two shovel-carrying beams G G, which are pivoted, at their front ends, `to pendants S S, by means ot horizontal transverse pins, which allow the said beams to vibrate eely, and thereby conform to the undulations of the ground over which the machine is drawn. I

The pendants S S are V-shaped, and the portions to which the beams G are pivoted are sustained against lateral thrust by means of the other portions of the pendants, which serve as braces. Severall holes are.

-made through the pendants, which will allow the front -ends of the beams G to be adjusted and set to work at dili'erent heights from the ground, for the purpose of regulating the pitch of the shovels.

The beams G G have standards J J secured to them in a rigid manner, and to these standards, shovels d d', which may be made of any suitable shape, are secured.

The beams G G extend back in rear of the axle B, and are prevented from having lateral motion by means of two pendentguides H H, which extend down some distance below the axle, and which are secured to the axle in such manner that they can be adjusted laterally and set at different distances apart.

The upper portions of the pendent guides H H are bent at right angles to the lower portions, and these upper portions are inserted through staples or clips g. g, which are secured to the back surface of the axle, as. shown in iig. 3. i By means of removable Apins h, inserted through the `inner staples g g, and through holes made through the said upper portions of the guides, these guides will be held rigidly in their places, and will prevent the shovels from being thrust laterally out of their places. By removing pins hA h, the pendent guides H H can be set further apart or nearer together.

l The beams G G have staples p p applied to their outer vertical sides, through which the pendent guides pass freely, which staples will allow the beams G to vibrate freely and to be raisedas shown in g. 4, but

will prevent these beams from moving out of place laterally.

vTwo spring goose-necks F F are secured fast to the front side of the axle B, and bent so as to extend over and downward back o f this axle.

These goose-necks are constructed so that they can be sprunglaterally, either to the right hand or left, and they have handles b b and hooks c c formed-on them, as shown in the drawings.

By pressing the rear springing vends of the goosenecks to one side, and raising the shovebcarrying beams or- HAR- G Gr high enough, staples e e, which are on said beams, i

can be attached to the hooks c c, Which Will support the said beams and their shovels in an elevated position, out of operation, as shown in fig. 4. lhe shovels are depressed into Working` position, when desired, by raising their beams slightly, and pressing the gooseneeks to one side, so as to detach the hooks c from the staples e.

The seat-board D is pivoted at one end to the rear extension of one of the hounds O, and at the other end itis connected to the rear extension of the opposite hound by means of a pin, a, by removing which the seat can be swung around out of the way of the attendant, when he desires 'to Walk behind the machine and have free access to the shovel-beams.

Having described our invention,

Vhat We claim as new, and desire to secure by Letters Patent, isl l. rlhe V-shaped brace-pendants S S, adjustable beams G G, stiff pendants H H, and staple-guides p p, arranged together in a oultivator, substantially as herein described.

2. The hooked-springe) goose-necks F, applied to axle B, and adapted to serve for holding up the shovel-carrying beams out of action, substantially as described.
